Hi i sold my WR400 awhile ago and have some bits spare that i got with the bike.

Ive got some piston rings but also have 6 extra rings and im not sure what they are.

4 of the rings are flat and 2 of them are grooved (in the pictures are 2 flat and 2 grooved.

I think they sit above and below the piston rings but im not totally sure, can anyone tell by the pics?

Those are oil control (bottom) rings. Two thin and a way part makes up one ring assy.

I suggest throwing them away.

I thought they might be almost useless!

Im gonna sell the rings on ebay so might aswell include them for the winning bidder

Thanks for the reply :worthy:
